FIBER-TREATING MACHINE.

SPECIFICATION forming part of Letters Patent No. 607,832, dated July 26, 1898.

Application filed July 3, 1896. Serial N0. 597,929. (No model.)

To aZZ whont it may concern:

Be it known that I, JOSEPH OHooUE'rrE, a subject of the Queen of Great Britain, residing at St. Hyacinthe, Province of Quebec, Do-

of an endless conveyor and a fiber-seizing de vice adapted to select and remove the fiber from the waste borne by said conveyor.

Cards and other machines used in preparing fiber to be spun throw off or drop a con siderable amount of the fiber along with dirt or extraneous matter. This mixture of fiber and dirt is commonly known as waste, and the fiber therein is lost or used in the manufacture of inferior articles.

I now proceed to describe my device in connection with a carding-machine 5 but of course I do not limit myself to this application.

In the accompanying drawings similar letters of reference indicate similar parts throughout the various views.

Figure 1 is a side view, partly broken away, of a well-known style of card with my device attached thereto. Fig. 2 is a detailside View, on enlarged scale, partly in section. Fig. 3 is an interior view of one of the side boards. Fig. 4 is a top view of same. Fig. 5 isa crosssection on line 5 5 of Fig. 1. Fig. 6 is an enlarged detail section on line (i 6 of Fig. 3.

A is the frame B, the main cylinder; 0, the tumbler; D, the bur-cylinder, and E the d0ffer of the card.

a is a supporting-bar adjustably attached to frame A by bolts 7). I

c is a supporting-plate adj ustably attached to frame A by bolts d.

eand e are journal-boxes vertically adj ust- 'able' on said bar by means of bolts f and f and screws 9 and g, respectively.

Supporting-plate c carries journal-box h, which is horizontally adjustable with reference to said bar a by means of said bolts 1) and cl and screw '6.

Fis an endless apron or belt passing around and operated in the direction of the arrow by means of rollers j and 7t, journaled, respectively, in-boxes eand h. It will of course be understood that similar journal devices are arranged upon the other side of the machine. Said apron Fextends under that portion of the card from which the waste falls and so that its delivery end is sufficiently near tumbler O for the purpose hereinafter described. Apron F is provided upon its under edges with strips Z of leather or other suitable sub-' stance.

G are side boards, one only being shown,

provided at their ends with slots m, by means of which they are supported on journals 6 and h. Said side boards are of sufficient width to extend a little above and a little below said apron F and bear upon their inner sides a grooved runway n, in the groove 0 of which said strips Z are adapted to run. Said side boards are also made extensible in any convenient manner, so that they may be readily fitted upon said horizontally-adjustable bearings e and h. In Figs. 3 and 4 is illustrated a device for rendering said side boards extensible. Each board is made in two parts 17 and q, and the runway on one part q is made horizontally adjustable there on by means of bolts 7', and the adjacent ends of the two parts of said runway are provided with a protecting metal covering 5.

H is a cylinder provided with teeth or bristles t, preferably of fine wire, and journaled in adjustable boxes 6. Said bristles are preferably straight, andI have found that the t should be, so proportioned with reference 5 to the diameter of cylinder H, its speed, and the speed of the traveling apron F that the dirt left after the bristles t have picked up the fiber from the waste will be discarded. This arrangement of'the bristles t on cylinder II is one of the principal features of my invention. In many such cards or fiber-treating machines there are braces or other stationary parts, for instance, as shown at '0,

Fig. 1, on which waste is apt to collect. To prevent this and to render the burden on apron F even and steady, I provide a vibrating shield or guard I. Said shield I, I preferably make of sheet metal bent soas to extend over the part c and above apron F. I also provide suitable means for regularly vibrating said shield I. A good device for this purpose is shown in Fig. 1. Said shield I is journaled on the frame A, and rigidly attached to said journal, so as to swing the same, is an arm w. Also journaled on said frame A is a cam-wheel 00, against which is held arm to by spring 1 Devices for cleaning the apron F may also be employed without departing from my invention. In adapting my device to some fiber-treating machines such cleaning device may be used instead of or in conjunction with the protecting side boards above described.

Of course it will be understood that roller j, cylinder H, and cam-wheel 5c are driven in the direction of the respective arrows from any convenient shafting.

I now proceed to describe the operation of my device. The several journals and the side boards having been adjusted so that apron F travels as shown and so that the bristles on cylinder II may pick up material on apron F and deliver it to tumbler O, the machine is started. The waste falling from the card will drop upon apron F and shield I. Cam-wheel a: rotates, and the cams thereon, Working against spring y on arm to, jar or vibrate shield I, so that said shield regularly delivers the waste dropping thereon to apron F. The waste thus falling upon apron F is carried thereby to the front of the machine. The side boards operate to keep the waste upon the apron, and the runways 77/, with their grooves 0 and strips Z, operate to prevent the device from becoming clogged with dirt or waste. As the waste is thus steadily delivered to the front end of the machine the parallel rows or strips of bristles t on rotating cylinder H catch and hold the fiber in said waste, the dirt or residuum being thrown out in front by the combined action of said bristles t and apron F. The fiber thus held on said bristles is conveyed by the continued rotation of said cylinder to the tumbler O, by which it is taken from cylinder H and passed on to the machine. The bristles t on cylinder II also tend to free the stock passing around tumbler C from extraneous matter.

I am aware that heretofore it has been attempted to separate the fiber from the waste and return said fiber to the fiber-treating machine; but in all such previous efforts the separation of fiber and dirt was attempted to be made on the apron or conveyer, the devices used for picking up the fiber being in all such cases so constructed that they would take up from the conveyer both fiber and dirt.

What I claim, and desire to secure by Letters Patent, is-

l. The device for treating waste from fibertreating machines which consists of a continuous conveyer, a cylinder at the delivery end of said conveyer, having bristles and clear spaces thereon, whereby the fiber and dirt contained in the waste borne on said-conveyer are separated, and the fiber held and the dirt thrown off, and means for operating said conveyer and cylinder substantially as described.

2. The device for treating waste from fibertreating machines which consists of a continuous conveyer, a cylinder at the delivery end of said conveyer, having straight bristles and clear spaces thereon, whereby the fiber and dirt contained in the waste borne on said conveyerare separated, and the fiber held and the dirt thrown off,'and means for operating said conveyer and cylinder, substantially as described.

3. The device for treating waste from fibertreating machines which consists of a continuous conveyer, a cylinder at the delivery end of said conveyer having parallel strips of bristles thereon, whereby the fiber contained in the waste borne on said conveyer, is separated from said waste and held, and means for operating said conveyer and said cylinder substantially as described.

4. In combination with a fiber-treating machine the device for saving and presenting to said machine the fiber contained in the waste therefrom,which consists of a continuousconveyer adapted to receive and convey the waste produced as the machine operates, a cylinder at the delivery end of said conveyer having bristles and clear spaces thereon whereby the fiber and dirt in said waste are separated, and the fiber held and returned to said machine and the dirt thrown off, and means for operating said device substantially as described.
